Verdict
The clearest difference is rating: RheoFit at 5.0 against Somnee's 3.7. RheoFit also leads on monetization model (free vs paid) and update cadence (weekly vs every 2 months). Somnee's advantage is ratings volume (71 vs 2) and review sentiment (64% vs 50%). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
RheoFit holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: Somnee has 71 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 64% of Somnee's written reviews are positive against 50% of RheoFit's, so the app with the better star average is not the one people write more warmly about.
Somnee ships an update every 2 months, RheoFit weekly. Both last shipped on September 29, 2026.
